Application filed J'u1y'21, 1921. Serial No. 486,486.

'1 all whom it may concern:

Be it known that we, EDWARD L. Lena- BERGER and ALBERT BRASHER, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Feeding Attachments for Power VVringers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it apper= tains to make and use the same. j The invention has relation to certain new and useful improvements in a wringer and has for its primary object the provision of a device of the character stated which will be of such construction and operation as to rethe pressure rollers.

duce to the minimum the liability of the operators hands being caught. or injured by the pressure rollers.

The invention has for another object the provision of a wringer of the character stated in which auxiliary feed rollers will be employed in connection with a movable endless belt which passes also between the pressure rollers and cooperates therewith in wringing or pressing the washing fluid out of the clothes or articles passing between The invention has for a further object the provision of a wringer of the character stated in which the auxiliary feed rollers will be adapted for cooperation with portions of the endless movable belt. at points between the outer guide rollers or idlers for the belt, and the pressure rollers. sothat the belt'will give and thereby eliminate danger of the pressure rollers crushing the hands of the operator while guiding the articles beneath I the feed rollers to pass to the pressure rollers.

The invention has for a further object the provision of awringer of the character statedin which the feed rollers will be resiliently forced toward the guide or feed belt without exerting enough pressure on the belt to cause a catching or pressing of the hands of the operator.

The invention has for a still further object the provision of a wringer of the character stated in which the belt will be mounted in a special manner with reference to the pressure rollers and the feed rollers on either side of and spacedfrom the pressure rollers, so as to properly guide the articles beneath either of the feed rollersand between the pressure rollers.

The invention has for-a still further object the provision of a wringer of the character stated in which the feed rollers will. be mounted in a. special manner and connected so that when one of the feed rollers is in operative position, the other feed roller will be automatically raised and held in elevated position to vprevent interference with the discharge of the pressed articles from the wringer.

The invention has for a still further object the provision of a wringer of the character stated in which the guide or feed belt may travel above and at a spaced distance with reference "to the drain board usually provided for such devices.

The invention has for a still further object the provision of a wringer of the character stated in which all of the rollers and the belt will be mounted in a special manner for the highest efliciency and cooperation with one another.

The invention has for still another object the provision ofa wringer of the character stated in which the feed rollers may be locked in the desired position so that either feed roller may operate with the feed belt tion and in which the parts may be readily assembled, secured together and the feed rollers mounted in bearings including pressure springs with tension regulating means provided therefor and the bearings movable in guide slots provided therefor in the supporting arms for the end guide rollers or idlers provided for the feed belts.

The invention has for a still further object the provision of a wringer of the character stated in which the supporting means for the end guide rollers or idlers of the feed belt and the feed rollers and mounting means therefor may be carried on the central post which may be mounted on the edge of the washer or on any other supporting device, as desired.

Figure 11 is a detail view of one of the pressure rollers and the mounting means therefor, removed.

Referring more in detail to the drawings which similar reference characters designate corresponding parts through the several views, 10 indicates the central posts which are arranged in pairs and spaced from one another. The posts of each pair are also spaced apart and have plates 11 positioned therebetween and extended vertically. These plates 11 serve as the bearing plates or bearing carrying plates within which the bearings l2 rollers 13 are mounted. These rollers 13 have reduced spindles 14 formed on their opposite ends and projecting into the bearings 12. Suitable springs 15 are provided between the posts 10 of each pair of central posts, to resiliently toward one another in order. that the pressure rollers 13 may be resiliently forced together to serve the purpose for which they are intended, as will be readily understood by parties familiar with this art.

Secured upon the outer face of the opposite or corresponding posts 10 of each pair, is a transversely extended rectangular frame 16, as will be readily understood by referring to the drawings. A bracket 17 extends outwardly from each end of each of the frames 16, to thereby provide a pair of brackets for each pair of posts 10 and rotatably mounted in the extreme outer ends of the pairs of brackets 17, are the extremities of spindles for the upper and lower pressure force the bearings 12;"

'- thetension of the springs 18 (see Figure 1) of the outer end guide .rollers or idlers 19 for the endless movable feed belt 20. Guide rollers or idlers 19 are of less diameter than the pressure rollers 13. The rolls 19 are so positioned that the upperrun of the belt 20 may be in a substantially horizontal plane and only raised slightly in its transverse central portion, at which point it passes between the pressure rollers and bears upon the upper face of the lower pressure roller, as shown clearly in Figure 4 of the drawings. This belt 20 may move in either direction, as may be desired, during operation of the device. A drain board 21 is provided beneath one end of the belt 20 in any suitable manner. Said drain board 21 may be formed as a part of the frame 16 or may be rigidly connected with the post 10, as desired. It will be understood that the drain board 21 is preferably spaced beneath the lower run of the belt 20 a suitable distance, so as not to interfere with the operation of the belt 20. The

brackets 17 have vertical guard plates 22 at their inner ends and projecting inwardly therefrom to turn the articles away from the ends of the upper pressure roller 13 and thereby reduce to the minimum the liability of the articles becoming caught between the ends of the pressure roller 13 and the frame. These guard plates 22 may be extended slightly toward the upper roller 13, as shown.

Each bracket 17 has a vertical pocket 23 formed in its main portion and opening at the upper edge thereof. These guide pockets 23 have central guide grooves 24, the purpose of which will presently appear. The grooves 21 are on the vertical walls of the pockets 23, as will be readily understood by referring to the drawings. (Figure 10.)

For cooperation with the feeding belt 20, feeding the articles to the pressure rollers 13,- we have provided a pair of feed rollers 25, which although shown as being longitudinally corrugated are not necessarily so constructed and which are spaced outwardly from or 'in front of the said feed rollers 25 being arranged so that while one roller 25 is raised, the other roller may be resting upon the upper run of the belt 20 for cooperation. therewith. The feed rollers 25 have reduced spindles or hub portions 26 at theirop posite ends mounted in suitable bearings in blocks 27 which are in turn fitted movably in the vertically'movable carrier frames 28. The bearing blocks 27 are vertically movable in the carrier frames 28, as clearly shown in the drawings, particularly Figures 6, 7 and 8 and the springs 29 are provided for yieldingly forcing them with the feed rollers 25 toward the lower ends of the carriers 28. Suitable tensioning or regulating screws 30 are threaded in the upper ends of the carriers 28 to regulate 29. The carriers pressure rollers 13,

pair at the same side of the machine and the rock arms are pivotally mounted at intermediate points on the upper ends of the plates 11, as shown at 33. It will be seen by referring to the drawings, particularly Figure 2, that when one pair of carriers 28 in its lowermost position to'permit the feed roller 25 to yieldingly rest on the feed belt and cooperate therewith, the other pair of carriers 28 is in its raised position to elevate the feed roller carried thereby. It will also be seen by referring to the drawings that a pair of upstanding guard plates 34cis provided to prevent the articles from passing under the ends of the feed rollers 25. The guard plates 34 are arranged at the inner faces of the brackets 17 adjacent the outer sides of the pockets 23'and are preferably extended slightly toward the rollers 25 for hich'they are provided.

As herein above indicated the feed rollers are adapted to receiverot-ary motion from the feed belt which is preferably provided with an adhesive surface such as of rubber or the like, similar to that provided for the pressure rollers, and free to rotate in either direction of movement of the upper run of the feed belt which is designed to receive motion from the pressure rollers which may be driven by any suitable power derived from any convenient source but not illustrated otherwise than that the spindles of the pressure rollers are extended beyond the frame and broken away as indicated in Figures 2, 3 and 5.

It will further be noted that the feed rollers are adapted for alternate use and bear upon unsupported intermediate portions of the feed belt between the terminal supporting rolls of the belt and the pressure rollers which constitute the driving element of the apparatus, each feed roller being designed for use in advance of the pressure rollers or in contact with the advance portion of the feed belt which is moving toward the pressure rollers, and owing to the unsupported characteristic of the belt at the point where the feed rollers come iii contact therewith, the hand of an operator passing inadvertently between the feed roller and the belt in placing an article-on the belt is not subject to crushing or any injury, by reason of the fact that the belt is adapted to yield downwardly or in a direction perpendicular to its plane as will be obvious by reference to the drawings and particularly Figure 4 thereof.

Moreover, as above indicated, the opposite A connecting feed rollers are yieldingly held in contact with the surface of the feed belt by means of the springs 29 which are adapted to be tensioned by means of the adjusting screws 30, but the carrier which supports the feed roller which is arranged in operative position should be locked in its depressed position, and for this purpose we employ a locking means generally designated at and consisting of latches '36 of which tapered heads 37 are adapted for engagement with sockets or notches 38 in the carriers and are yieldingly held in engaging relation with said sockets by springs 39 coiled as illustrated upon the stub spindles 40 upon which the arms or shanks of the latches are mounted. Latches 36 have grips or handles 41 projecting outward through slots 42 in brackets 17, and preferably the opposite latches, which'are designed to secure the complemental carrier blocks supporting each feed roller, are connected by a transverse brace rod 43 to insure cooperative action of the opposite latch members and enable the operator to actuate both latches from one side of the machine.

It will further be noted that the lower run of the feed belt bears against the under side of the lower pressure roller 13 and that suitable tensioning means are provided for the supporting rollers 19 of the feed belt,

said tensioning means in the construction illustrated consisting of adjusting bolts 44 threaded in suitable guides 45 which receives the extremities of the spindles 18 which carry the guide rollers 19. (See Figure 4).

It will further be observed that where as in certain of the principal features the apparatus herein disclosed follows the lines of the conventional or typical forms of wrin er com risin 'su ortin 1! posts, frames mounted on said supportingv posts, pressure rollers mounted in said supporting posts, arms extended from said frames in pairs, guide rollers mounted in said arms, a feed belt extended around said guide rollers and passing said pressure rollers to cooperate therewith, feed rollers mounted above said feed belt, means connecting said. feed rollers to retain one of the said rollers in operative position with relation to saidbelt and the remaining feed roller in inoperative position, and locking means for said feed'rollers. r v
